[Objective]The aims of this study are to determine the soil desiccation characteristics of a typical plantation in the Baiyu Mountain area, and to provide theoretical basis for reasonable selection and sustainable development of plantation in Baiyu Mountain area. [Methods]The plantations with 40 years of vegetation restoration(Populus×hopeiensis Hu & Chow, Pinus tabulaeformis, and Pinus sylvestris var. mongholica Litv.)were taken as the samples. The barren grassland was taken as the control. Artificial soil drilling method was used to study the drying characteristics and influencing factors of 0—5 m soil in the artificial forest. [Results](1)The average soil water content of different plantations was in the order:grassland(4.95%)>Pinus sylvestris var. mongholica Litv.(4.49%)>Populus×hopeiensis Hu & Chow(4.39%)>Pinus tabuliformis(2.44%).(2)The soil dry layer existed in different plantations and the formation depth and thickness of the dry layer were basically the same, but the average water content of the soil in the dry layer was different, the lowest value was observed in Pinus tabulaeformis and the highest value was observed in the wasteland.(3)The soil desiccation index of different plantations followed the order:Pinus tabuliformis (69.75%)>Populus×hopeiensis Hu & Chow(28.83%)>Pinus sylvestris var. mongholica Litv.(26.73%)>grassland(17.05%).(4)Correlation analysis and multiple linear regression model showed that silt, sand and depth were the main factors affecting soil desiccation characteristics of Pinus sylvestris var. mongholica Litv., Pinus tabulaeformis and Populus×hopeiensis Hu & Chow, respectively. [Conclusion]The soil desiccation degree of Pinus sylvestris var. mongholica Litv. was the lowest after 40 years of planting, Pinus sylvestris var. mongholica Litv. could be used as the best choice for afforestation of typical plantation in Baiyu Mountain area.
